Patent GB-1008066-A (GB)
Title: A process for the treatment of solutions of products formed by the fission of uranium-molybdenum alloys
Inventor: LEFEVRE JEAN
IPC: G21C19/46
Filed: 1963-03-28
Abstract: A nitric acid solution containing molybdenum, cesium and zirconium is treated with phosphoric acid in order to recover the cesium and the zirconium from the solution.  The solution is concentrated by evaporation, and during this, quantities of phosphoric acid are progressively added to the solution in amounts at least equal to the stoichiometric amount corresponding to the transformation of all the molybdenum into phosphomolybdic acid and all the zirconium into zirconium phosphate. This precipitates the zirconium as the phosphate and the cesium as the phosphomolybdate. The mixed precipitate, separated by filtration from the concentrated phosphomolybdic acid solution, is treated with a caustic alkali, e.g. NaOH, when the cesium dissolves leaving the zirconium as an insoluble hydroxide. Reacidification of the cesium solution obtained re-precipitates the cesium as the phosphomolybdate.  During the evaporation the nitric acid concentration is kept substantially constant, e.g. at about 2 N., by means of the addition of formaldehyde, and the evaporation is preferably stopped after a molybdenum concentration of 100 g./litre has been reached.  The cesium phosphomolybdate finally obtained may be further processed to recover the cesium.  The precipitate is washed with a solution of nitric acid and then decomposed with an alkaline earth metal hydroxide, e.g. baryta water, and the solution containing cesium hydroxide and excess baryta water is separated. The barium in this solution is precipitated either as carbonate using CO2 or as the sulphate using sulphuric acid, and the filtrate obtained contains the desired cesium as carbonate or sulphate.  The process is used for separating fission products from radioactive waste solutions.

Filed: 1935-04-24
Abstract: 460,290. Valves. CARROLL, C. F. April 24, 1935, No. 12363. [Class 135] [Also in Group XI] The handle or other suitable part of a blowpipe or torch for metal cutting and working operations is fitted with reducing valves controlling the pressure of the gases passing to the mixing chamber, so that the pressure at the jet or jets is maintained substantially constant and means in advance of the reducing valves for controlling the rate of supply of the gases. In the blowpipe shown oxygen issues from a nozzle 8 into a chamber 14 at a reduced pressure maintained constant by a valve 9 connected to a plate 11 secured to an aneroid chamber 12 containing an adjustable spring 16. The fuel gas similarly issues through a nozzle 59 into a chamber 65 at a reduced pressure maintained constant by a valve 60 connected to an aneroid chamber 63. From the chambers 14, 65 the gases pass through valves 28, 70, passages 36, 75, and a diaphragm 39 formed with metering orifices 38, 40, in the handle to a mixing chamber 79 at the base of burner nozzle 42. The valves 28, 70 are simultaneously operated against the pressure of springs 34, 71 by a rotatable ring 29 formed with cam-grooves 31, 73. Oxygen under high pressure may be supplied to the cutting jet passage 43 through a valve 49 operated by a push-button 52 and connected to the oxygen inlet passage 53. The diaphragm 39 may be replaced by singleapertured movable valve rings which are movable together relatively to a series of holes of graduated diameter through which the oxygen and fuel gas issue into the mixing chamber. The pressure-reducing valves may alternatively be operated through lever mechanism by flexible diaphragms subjected to the pressure of the incoming gases.

Abstract: 836,043. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 11, 1958 [April 17, 1957], No. 12618/57. Class 39(4). A support structure for fuel elements of a nuclear reactor comprises a nest of tubes having means holding them in face contact with one another on hexagonal sections in the tubes and the tubes intersecting with one another in other sections of greater area than the area of the hexagonal sections, the tubes having their centres corresponding with the corners of a symmetrical hexagonal lattice and arranged so that around any hexagon of the lattice tubes of greater length alternate with tubes of lesser length and arranged so that the tubes are fixed longitudinally to one another by their intersecting portions. Fig. 1 shows one of the long tubes 1 which is generally cylindrical but provided with six flat external faces 2 forming a regular hexagon, each face 2 having a central vertical slot. The tube 1 is provided with three equispaced shallow slots 4 and three equispaced deep slots 5 aligned above and below alternate faces 2. The short tubes, Fig. 2, each confines a cylindrical member 7 provided with six flat faces 8 each having a central vertical slot. The tube is provided with three equispaced slots 10 and three equispaced slots 11 aligned above and below alternate faces 8. As shown in Fig. 3 a long tube 1 and short tube 7 can engage one another with the portion 7a above slot 10 of the short tube engaging slot 4 of the long tube, and the portion 7b engaging slot 5. Thus an array of tubes can be built up with the long and short tubes alternating in hexagonal sections ; the array may be star shaped and the long tubes may extend between top and bottom plates provided with apertures to receive the tubes, the apertures preferably being slightly displaced from a symmetrical arrangement so that the tubes are bowed concave as seen from the centre. In use the tubes are charged with tubular fuel elements which are held in position by spaced bands of cooling fins provided on the fuel elements ; the concave bowing of the tubes prevents the fuel elements bowing convexly which would increase the reactivity of the core. Specification 813,131 is referred to.

Filed: 1941-10-10
Abstract: 547,786. Capping bottles &c. AKTIEBOLAGET ALKA ALUMINIUMKAPSLAR. Oct. 10, 1941. No. 13094. Convention date, Oct. 2, 1940. [Class 125 (ii)] A device for capping bottles, flasks and the like of slightly differing heights comprises an elastic ring 7 actuated by a piston 8, the piston being actuated by relative movement between a member 4 within which the piston operates and a carrier member 3. A lever 10 bearing upon the piston 8 is pivoted upon the member 4 and is operatively connected to a lever 19 pivoted upon the carrier member 3 by a spring 14. The lever 19 is actuated by a pin 27 carried by a member 26 slidably mounted within the carrier member 3 and in turn operated by a wedge 22 carried by the member 4. In operation, when the carrier is lowered towards the bottle, the bottle cap engages the piston 8 and prevents momentarily its further downward movement, and the member 4 is moved axially of the carrier 3 to operate the member 26 to actuate the lever 19, so that under control of the spring 14, the piston is lowered to compress the ring 7 about the cap. A small-diameter piston 9 acts under spring control to retain the cap in position upon the bottle. The arrangement of wedge 22 engaging between rollers 24, 25 mounted upon the carrier 3 and sliding member 26 respectively produces a very small movement of the member 26 and the lever 19.
